How Solar Energy Works to Power Gadgets and Structures
Many gadgets (ranging
from the common hand-held calculators to satellites
in outer space) are dependent on solar energy
somehow to power their operations. But have
you ever wondered how solar energy systems
actually function?
The first component of a functional solar
energy system is the solar panel or solar
panels which are made of semiconductor materials
like silicon. These solar panels (also called
solar photovoltaic panels) are the component
which gathers sunlight for us when the rays
of the sun hit the surface of the solar energy
panels.
The next stage is for the solar energy gathered
through solar panels to be changed into pure
energy for us. This is the process called
solar thermal application. In solar thermal
application, the solar energy is employed
to heat liquids or air so that the solar energy
is altered into a state of pure energy by
the solar photovoltaic cells.
One reason that solar photovoltaic cells are
quite expensive to use for solar-powered gadgets
is that they are very costly to manufacture.
The process by which solar energy systems
become so costly is triggered by the high
cost of raw materials for the systems, as
well as by the low demand for solar energy
systems. If raw materials did not cost so
much to source and supply to manufacturers
of solar energy systems, then the final cost
and price of these solar energy systems would
not be so high. And if demand for such solar
energy systems were to go up, that would mean
manufacturers could afford to lower the price
of their solar energy systems even further.
The ultimate aim of solar energy systems manufacturers
is to achieve break-even point and then turn
a profit (like all businesses do.)
There are some solar energy systems, which
really make a lot of sense to put up, like
solar-thermal power plants. One reason these
types of solar energy systems are sensible
to put up is because there will be no need
to charge consumers for the cost of transmission
through the standing power lines or underground
electrical cable lines. Actually, if home
solar energy systems were to be used, there
would be no need for such lines at all. Everything
would be processed on site at the home of
the consumer by the home solar energy systems.
Another way we can use solar energy without
much hassle is to simply make our homes more
dependent on daylight to light up the insides
of the building. This means using roofing
and window materials (such as translucent
roofing sheets) that allow sunlight to enter
and light up our room. In countries that experience
less hours of sunlight, this type of system
may act as a greenhouse and help heat up our
structures better without resorting to costly
heating systems. Coupled with adequate insulation,
such solar energy systems would be perfect
for heating up ourhabitats within our homes
and offices without requiring much effort
on our part, even for monitoring the performance
of our solar energy systems themselves.
